Effect of pepper and salt blends on microbial quality of quanta: Ethiopian dried red meat

This study was conducted to assess the effect of spice blends varying in salt and pepper concentrations on the microbial quality of Quanta: Ethiopian dried red meat. The experiment had seven treatments: 25% spices, 25% salt, and 50% pepper (T1); 25% spices, 20% salt, and 55% pepper (T2); 25% spices, 15% salt, and 60% pepper (T3); 25% spices, 10% salt, and 65% pepper (T4); 25% spices, 5% salt, and 70% pepper (T5); 100% spices (without salt and pepper), a positive control (T6); a negative control without any added ingredient (T7). Microbiological analyses were performed initially on the raw sliced meat and spice blends, and after application of the treatments on the 10th and 20th days of drying. High initial loads of total bacteria (APC) and Enterobacteriaceae (EC) were observed in the raw meat samples and spice blends and increased over the drying periods (10 and 20 days) in all treatments. No significant difference (p>0.05) was observed among the treatments (T1-T7) for APC and EC at a given drying period and between the drying periods. Salmonella spp. was not detected in any of the seven treatments either on the 10th and 20th days of drying. However, Escherichia coli was detected in six (T1-T6) of the dry meat samples except in T7 both on the 10th and 20th days of drying suggesting that the spice blends served as a source of contamination of the dried meat samples with E. coli. However, the spice blends used in combination with drying were effective in inhibiting the growth of Salmonella species in the dry meat samples. Spices as well as the raw meat used for Quanta preparation should be produced and handled under hygienic conditions to minimize the microorganisms that they harbor

The impact of dietary risk factors on the burden of non-communicable diseases in Ethiopia: findings from the Global Burden of Disease study 2013

Background: The burden of non-communicable diseases (NCDs) has increased in sub-Saharan countries, including Ethiopia. The contribution of dietary behaviours to the NCD burden in Ethiopia has not been evaluated. This study, therefore, aimed to assess diet-related burden of disease in Ethiopia between 1990 and 2013. Method: We used the 2013 Global Burden of Disease (GBD) data to estimate deaths, years of life lost (YLLs) and disability-adjusted life years (DALYs) related to eight food types, five nutrients and fibre intake. Dietary exposure was estimated using a Bayesian hierarchical meta-regression. The effect size of each diet-disease pair was obtained based on meta-analyses of prospective observational studies and randomized controlled trials. A comparative risk assessment approach was used to quantify the proportion of NCD burden associated with dietary risk factors. Results: In 2013, dietary factors were responsible for 60,402 deaths (95% Uncertainty Interval [UI]: 44,943-74,898) in Ethiopia—almost a quarter (23.0%) of all NCD deaths. Nearly nine in every ten diet-related deaths (88.0%) were from cardiovascular diseases (CVD) and 44.0% of all CVD deaths were related to poor diet. Suboptimal diet accounted for 1,353,407 DALYs (95% UI: 1,010,433-1,672,828) and 1,291,703 YLLs (95% UI: 961,915-1,599,985). Low intake of fruits and vegetables and high intake of sodium were the most important dietary factors. The proportion of NCD deaths associated with low fruit consumption slightly increased (11.3% in 1990 and 11.9% in 2013). In these years, the rate of burden of disease related to poor diet slightly decreased; however, their contribution to NCDs remained stable. Conclusions: Dietary behaviour contributes significantly to the NCD burden in Ethiopia. Intakes of diet low in fruits and vegetables and high in sodium are the leading dietary risks. To effectively mitigate the oncoming NCD burden in Ethiopia, multisectoral interventions are required; and nutrition policies and dietary guidelines should be developed
